APPARATUS FOR THE INTERMITTENT DISCHARGE 0F SEWAGE, dc.

SPECIFICATION forming part of Letters Patent No. 316,567, dated April 28, 1885..

Application filed July 26, 1884. (No model.)

To all whom it may concern:

Be it known that I, GEORGE S. PIERsoN, a citizen of the United States, residing at Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented a new and useful Apparatus for the Intermittent Discharge of Sewage and other Liquids, which invention has not been patented to myself or to others with my consent or knowledge in any country, of which the following is a specification.-

My invention relates to improvements in apparatus whereby sewage or other liquid is collected and intermittently discharged; and the objects of my invention are, first, to provide a valve or gate and accessory mechanism by which the liquid may be intermittently discharged; second, to provide for a free passage of air at all times between the discharging tank or vessel, the sewer or receptacle into which the liquid is discharged, and the outer air, each and all; third, to provide an overflow independent of the valve or gate. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a view of the apparatus in vertical section and elevation; Fig. 2, a section of the ventilating-pipe and inclosing-basin; Fig.

,3, an enlarged sectional view of the dischargevalve and accessory mechanism; Figs. 4 and 5, exterior and interior views of the valve and its seat; Figs. 6, 7, 8, and 9, views in detail of the accessory mechanism.

Similar letters refer to similar parts th roughout the several views.

A is a tank situated at the head of a sewer, or at any point where the intermittent discharge of a liquid is desired. It is provided at the top with a cover, B, perforated to allow the passage of gases, and under the perforations of which may be hung a dust-pan, O. The tank A is provided at the bottom with a funnel-shaped discharge-pipe, D, having a flange, e, to which is bolted a ring, F, havit is desired to have the liquid at the time of discharge from the points 0 and p.

Q is a cook connecting with a supply-pipe. R is a pipe or passage connecting the discharge-pipe with the interior of the tank A independently of the valve H. A branch may also be extended upward and closed byacover suitable for allowing inspection, or it may terminate in a basin covered by a ventilatingplate, as shown in Fig. 2, or be carried above the roof of a building,or to any desired point. in which case the perforations in the cover B may be dispensed with. The pipe B may also be within the tank. The funnel-shaped dischargepipe D, vring F, and valve H, with its accessory mechanism, are constructed preferably of metal. The valve seat and face may be cast with a slightly-raised projection, which may be formed in a lathe or otherwise to truly-opposing sur faces properly compressing the gasket, which is preferably of rubber. .,eontrolling the position of the central pivot in the locking-levers to form a rigid brace with the least depression of the central pivot below a right line joining the extreme pivots, is preferably constructed as shown, having a bolt adjustable in a slot oblique to the direction of strain, as allowing a more accurate and permanent adjustment.

The tank A, pipe R, and discharge-pipe D being in position, I apply the gasket 9 to the interior face of the ring F, and by means of the mechanism hereinbefore described adjust the several accessory parts truly in their relative position on the ring F, which I then The adjustable stop bolt to theflange e and suspend the float in the position desired.

Referring now to Fig. 1, the operation of the device is as follows: The several parts be:

yields laterally in the direction of the float,

position,-causes it to close when the liquid stops running over it, and the several parts assume their first position. Should the mechanism fail to act from any cause, the liquid overflows through the pipe R and passes to the discharge-pipe. The tank may be discharged by the hand at any time desired.

The pipe R, in connection with the perforated cover 13, or the extension of its branch, serves also as a ventilating-pipe, allowing a free back draft in the discharge-pipe independent of the valve, and upon the tank being emptied and the valve closed afreeinflow of the atmosphere following the liquid in its discharge, which is thus greatly accelerated.

It also, in the case of a tank and sewer, by

connecting the interior of the tank and sewer, tends to prevent freezing in the tank.

Though preferring the arrangement and form of the various parts here shown, I do not limit myself to them in construction, except where especially referred to in the claims.

'l'also propose in some cases to combine the outwardly-projected weighted arm.

float and the overbalaneing weight. y I It is obvious that the apparatus as shown, though it may be cheaply constructed, can be adjusted with the utmost accuracy in all its Working parts, and can be readily readjusted without removing the ring; or, if desired, the whole may be readily'removed', fitted, and'replaced. j j I am aware that prior to my invention tanks or vessels for the intermittent discharge of sewage or other liquids have been supplied with valves acting automatically, and that such Valves havebeen internally located in the dis charge-pipe of the tank and actuated by an I theregore do not claim such combination, broadly;

1. The improved apparatus herein described, consisting, essentially, of a tank in combination with a valve and its actuating mechanism adapted to discharge the contents of the tank intermittingl y,- and air-passages connecting the :3 interior of the tank, its outlet, and the outer valve and actuating mechanism adapted to disair,-feach:and all. 2. In combination with atank, the improved charge the contents of the tank intermittingly,

the same consisting in a valve opening outwardly .and actuated. by an overbalancing weight, and a system of levers adapted to be held in equilibrium by a stop upon slightly passing the point of greatest compression of the valve upon its closing.

3, The combination, with a tank, of a valve adapted to be automatically actuated by an overbalancing weight, a float, and a system of levers adjusted to be held in equilibrium after slightly passing, in their closing motion, the point of greatest compression of the valve, and also adjusted to release the valve through the action of a float.

4. In the herein-described apparatus, the combination, with a discharging-valve, of an air-passage from the interior of the tank terminating in a basin havinga perforated cover, substantially as in Fig. 2.

5. In the improved apparatus herein de= scribed, the combination, with a dischargingvalve, of an 'untrapped air-passage connecting locking levers, the'outwardly opening' valve,
